Development along with optical image technology, the camera lens module is used widely in various imaging devices such as digital camera, video camera and (is seen also Capturing images with digital still cameras, Micrc, IEEE Volume:18, issue:6, Nov.-Dec.1998 Page (s): 14-19).Be integrated with the portable electron device such as mobile phone, notebook of camera lens module, obtain numerous consumers' favor especially.
A kind of camera lens module 20 of the prior art as shown in Figure 3, it comprises a lens barrel 202, and is successively set on first eyeglass 204 in the lens barrel 202, anti-dazzling screen 210, the second eyeglasses 206, interval body 212 and prismatic glasses 208 from the object side to image side.Optical elements such as eyeglass in the lens barrel 202 generally are to be fixed in the lens barrel 202 by a glue.
Yet when if the fixing insecure or glue of above-mentioned optical element point glue wears out, the intensity of camera lens module 20 can descend.As shown in Figure 4, when camera lens module 20 is heated, eyeglass in the camera lens module 20 may be out of shape because of expanded by heating, because first eyeglass 204 bears against the supporting part 2022 of lens barrel 202, so each optical element in the camera lens module 20 expands or displacement towards the direction away from lens barrel 202 supporting parts 2022 along the direction of optical axis 214, thereby reduce the stability of camera lens module 20 inner structures, and then reduce the image quality of camera lens module 20.Similarly, when camera lens module 20 was given a shock, each optical element in the camera lens module 20 may be along the direction of optical axis 214 towards the direction displacement away from lens barrel 202 supporting parts 2022, thereby reduced the stability of camera lens module 20 inner structures.
Summary of the invention
In view of this, be necessary the camera lens module and the assemble method thereof that provide a kind of structural stability better.
A kind of camera lens module comprises: a lens barrel, and this lens barrel has relative first end and the second end, and this first end has a supporting part, and this second end is provided with internal thread; One is housed in the lens unit in this lens barrel, and this lens unit bears against on this supporting part; One locating ring, this locating ring is provided with external thread, and this locating ring and this lens unit are fitted, and pass through threaded engagement with this lens barrel, so that this lens unit is fixed in this lens barrel.
A kind of assemble method of assembling above-mentioned camera lens module, it may further comprise the steps: this lens unit is assembled in this lens barrel, and this lens unit is born against on the supporting part of this lens barrel; And this locating ring screwed in this lens barrel, make the screw-internal thread fit of external thread and this lens barrel of this locating ring, and this locating ring is screwed, so that this lens unit is fixed in this lens barrel.
With respect to prior art, the locating ring of camera lens module of the present invention and lens barrel secure fit limit the substantially invariable receiving space of volume between the supporting part of locating ring and lens barrel.When the lens unit in the camera lens module is heated, locating ring can reduce or eliminate the expanded by heating distortion of each optical element, stop lens unit to expand or displacement, thereby improve camera lens module internal stability of structure, and then promote the image quality of camera lens module along the direction of optical axis.In like manner, when the camera lens module was given a shock, locating ring can stop lens unit to be subjected to displacement along the direction of optical axis equally, thereby improved camera lens module internal stability of structure, and then promoted the image quality of camera lens module.In addition, the camera lens module that adopts above-mentioned assemble method to obtain has same advantage.

Fig. 3 is the diagrammatic cross-section of a kind of camera lens module in the prior art;
View when Fig. 4 is an optical element expanded by heating in the camera lens module shown in Figure 3.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
See also Fig. 1, the camera lens module 10 of preferred embodiment of the present invention comprises a lens barrel 102 and is housed in a lens unit in the lens barrel 102.Lens unit comprises first eyeglass 104 from the object side to image side successively, anti-dazzling screen 110, the second eyeglasses 106, interval body 112, the prismatic glasseses 108 and locating ring 114.Lens unit has an optical axis 116.
Locating ring 114 is circular, and the center has a through hole 1146, and through hole 1146 allows light to pass locating ring 114.Locating ring 114 has a side 1142 and one and the end face 1144 that joins of this side 1142.The side 1142 of locating ring 114 is provided with external thread, and external thread is used for fixing with the screw-internal thread fit of lens barrel 102.Fit in the end face 1144 of locating ring 114 and the surface of prismatic glasses 108 1082.Locating ring 114 can be got by metallic, preferably, adopts the higher metal of hardness, as iron, stainless steel etc.Be appreciated that in order more firmly locating ring 114 to be fixed in lens barrel 102, can be at the threaded engagement place point glue of locating ring 114 with lens barrel 102.
Because locating ring 114 and lens barrel 102 secure fit limit the substantially invariable receiving space of volume between the supporting part 1030 of locating ring 114 and lens barrel 102.Optical element in camera lens module 10 is (as first eyeglass 104, second eyeglass 106 and the prismatic glasses 108) when being heated, locating ring 114 can reduce or eliminate the expanded by heating distortion of each optical element, stop above-mentioned optical element to expand or displacement along the direction of optical axis 116, thereby improve the stability of camera lens module 10 inner structures, and then promote the image quality of camera lens module 10.
